Now that we fixed the sub-ns handling for CLOCK_MONOTONIC_RAW,
remove the duplicitive tk->raw_time.tv_nsec, which can be
stored in tk->tkr_raw.xtime_nsec (similarly to how its handled
for monotonic time).

(cherry pick from commit 3d88d56c5873f6eebe23e05c3da701960146b801)
Due to how the MONOTONIC_RAW accumulation logic was handled,
there is the potential for a 1ns discontinuity when we do
accumulations. This small discontinuity has for the most part
gone un-noticed, but since ARM64 enabled CLOCK_MONOTONIC_RAW
in their vDSO clock_gettime implementation, we've seen failures
with the inconsistency-check test in kselftest.
This patch addresses the issue by using the same sub-ns
accumulation handling that CLOCK_MONOTONIC uses, which avoids
the issue for in-kernel users.
Since the ARM64 vDSO implementation has its own clock_gettime
calculation logic, this patch reduces the frequency of errors,
but failures are still seen. The ARM64 vDSO will need to be
updated to include the sub-nanosecond xtime_nsec values in its
calculation for this issue to be completely fixed.

The vdso tries to check for a NULL res pointer in __kernel_clock_getres,
but only checks the lower 32 bits as is uses CBZ on the W register the
res pointer is held in.
Thus, if the res pointer happened to be aligned to a 4GiB boundary, we'd
spuriously skip storing the timespec to it, while returning a zero error code
to the caller.
Prevent this by checking the whole pointer, using CBZ on the X register
the res pointer is held in.

Pull f2fs updates from Jaegeuk Kim:
"In this round, we introduce sysfile-based quota support which is
required for Android by default. In addition, we allow that users are
able to reserve some blocks in runtime to mitigate performance drops
in low free space.
Enhancements:
- assign proper data segments according to write_hints given by user
- issue cache_flush on dirty devices only among multiple devices
- exploit cp_error flag and add more faults to enhance fault
injection test
- conduct more readaheads during f2fs_readdir
- add a range for discard commands
Bug fixes:
- fix zero stat->st_blocks when inline_data is set
- drop crypto key and free stale memory pointer while evict_inode is
failing
- fix some corner cases in free space and segment management
- fix wrong last_disk_size
This series includes lots of clean-ups and code enhancement in terms
of xattr operations, discard/flush command control. In addition, it
adds versatile debugfs entries to monitor f2fs status"

Allowing binder to expose the 64-bit API on 32-bit kernels caused a
build warning:
drivers/android/binder.c: In function 'binder_transaction_buffer_release':
drivers/android/binder.c:2220:15: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]
fd_array = (u32 *)(parent_buffer + fda->parent_offset);

drivers/android/binder.c: In function 'binder_fixup_parent':
drivers/android/binder.c:2511:18: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]
This adds extra type casts to avoid the warning.
However, there is another problem with the Kconfig option: turning
it on or off creates two incompatible ABI versions, a kernel that
has this enabled cannot run user space that was built without it
or vice versa. A better solution might be to leave the option hidden
until the binder code is fixed to deal with both ABI versions.

The two commands are for native DSI panels without a bridge

In addition,the two command will cause extra wait for about
